You're using salt as a medication. Meds have side effects. There are bad things they do as well as good ones. Aspirin attacks the stomach lining and can give you stomach ulcers. Paracetamol attacks the liver and can kill you at levels starting at only twice that used for pain relief. Citalopram makes you feel like puking. It's always a balance of benefit against deficit. Short term salt use is less harmful than ich infestation, and it's less harmful than nitrite poisoning, for example.
This is worth remembering; salt is not an alternative to medication; it is a medication.
